Sympathetic activation in congestive heart failure: an updated overview.
Guido Grassi; Fosca Quarti-Trevano; Murray D Esler
HEART FAILURE REVIEWS - 12 Dec 2019
Conclusive evidence demonstrates that the sympathetic nervous system activation is a hallmark of congestive heart failure. This has been shown via a variety of biochemical, neurophysiological, and neuroimaging approaches for studying human sympathetic neural function. The sympathetic activation appears to be an early phenomenon in the clinical course of the disease, closely related to its sever...

LANCET (LONDON, ENGLAND) - 14 Dec 2019
The relevance of blood lipid concentrations to long-term incidence of cardiovascular disease and the relevance of lipid-lowering therapy for cardiovascular disease outcomes is unclear. We investigated the cardiovascular disease risk associated with the full spectrum of bloodstream non-HDL cholesterol concentrations. We also created an easy-to-use tool to estimate the long-term probabilities for...

EUROPEAN HEART JOURNAL - 14 Dec 2019
The overall lifetime risk of heart failure (HF) is similar between men and women, however, there are marked sex differences in the landscape of this condition that are both important and under-recognized. Men are predisposed to HF with reduced ejection fraction (HFrEF), whereas women predominate in HF with preserved ejection fraction (HFpEF). Sex differences are also notable in the penetrance o...
Assessment of Predictors of Left Atrial Volume Response to a Transcatheter InterAtrial Shunt Device (from the REDUCE LAP-HF Trial).

THE AMERICAN JOURNAL OF CARDIOLOGY - 15 Dec 2019
In patients with heart failure and preserved or mildly reduced ejection fractions (EF ≥40%), implantation of an interatrial shunt device (IASD) resulted in heterogenous changes of the left atrial (LA) volume. Baseline characteristics that correlate with a favorable decrease in LA volume are unknown. We hypothesized that a larger ratio of left to right atrial volume at baseline would correlate s...

INTERNAL MEDICINE JOURNAL - 16 Dec 2019
Cancer therapy related cardiac dysfunction (CTRCD) is an area of increasing focus, particularly during the survivorship period, for paediatric, adolescent and adult cancer survivors. With the advent of immunotherapy and targeted therapy, there is a new set of mechanisms from which paediatric and young adult patients with cancer may suffer cardiovascular injury. Furthermore, cardiovascular disea...

HYPERTENSION (DALLAS, TEX. : 1979) - 16 Dec 2019
Heart failure is associated with sympatho-βAR (β-adrenoceptor) activation and cardiac fibrosis. Gal-3 (galectin-3) and K3.1 channels that are upregulated in diverse cells of diseased heart are implicated in mediating myocardial inflammation and fibrosis. It remains unclear whether Gal-3 interacts with K3.1 leading to cardiac fibrosis in the setting of βAR activation. We tested the effect of K3....

EUROPEAN HEART JOURNAL CARDIOVASCULAR IMAGING - 17 Dec 2019
Left atrial (LA) strain is a prognostic biomarker with utility across a spectrum of acute and chronic cardiovascular pathologies. There are limited data on intervendor differences and no data on intermodality differences for LA strain. We sought to compare the intervendor and intermodality differences between transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) derived LA s...

JACC. CARDIOVASCULAR IMAGING - 18 Dec 2019
The purpose of this study was to investigate the effect of the temporal and observer variability of cardiac magnetic resonance (CMR)-measured native T, T, and extracellular volume fraction (ECV) and serum biomarkers for the detection of cancer-therapeutics-related cardiac dysfunction (CTRCD).1Biomarkers and serial quantitative CMR tissue characterization may help identify early myocardial chang...

A Nirenberg; H Steinman; J Dixon; A Dixon
JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY AND VENEREOLOGY : JEADV - 19 Dec 2019
Merkel cell carcinoma (MCC) is an aggressive tumour with neuroendocrine differentiation. Clinically significant differences within the entity we know as MCC are apparent. This review aims to evaluate the evidence for differences in tumours within Merkel cell carcinoma and to stratify these. A literature search of research pertaining to various characteristics MCC was undertaken from 1972, when ...

HEART RHYTHM - 19 Dec 2019
Female gender is associated with an increase in recurrence of atrial fibrillation (AF) following catheter ablation (CA). Although AF is more common in men, women make up a significant proportion with persistent AF (PsAF).To determine if multiple ablation procedures improves arrhythmia outcomes in females with PsAF compared to men.We performed a multicentre observational study to determine the l...

PLOS BIOLOGY - 20 Dec 2019
Cholesteryl ester transfer protein (CETP) inhibition reduces vascular event risk, but confusion surrounds its effects on low-density lipoprotein (LDL) cholesterol. Here, we clarify associations of genetic inhibition of CETP on detailed lipoprotein measures and compare those to genetic inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). We used an allele associated with lower ...

NATURE COMMUNICATIONS - 20 Dec 2019
Recent genome-wide association studies in stroke have enabled the generation of genomic risk scores (GRS) but their predictive power has been modest compared to established stroke risk factors. Here, using a meta-scoring approach, we develop a metaGRS for ischaemic stroke (IS) and analyse this score in the UK Biobank (n = 395,393; 3075 IS events by age 75). The metaGRS hazard ratio for IS (1.26...

CIRCULATION - 23 Dec 2019
Individuals with left ventricular hypertrophy (LVH) and elevated cardiac biomarkers in middle-age are at high risk for the development of heart failure with preserved ejection fraction (HFpEF). However, it is unknown what the pathophysiological underpinnings of this high risk state may be. We tested the hypothesis that patients with LVH and elevated cardiac biomarkers would demonstrate elevated...
Fat for fuel: lipid metabolism in haematopoiesis.
Gerard Pernes; Michelle C Flynn; Graeme I Lancaster; Andrew J Murphy
CLINICAL & TRANSLATIONAL IMMUNOLOGY - 01 Jan 2019
The importance of metabolic regulation in the immune system has launched back into the limelight in recent years. Various metabolic pathways have been examined in the context of their contribution to maintaining immune cell homeostasis and function. Moreover, this regulation is also important in the immune cell precursors, where metabolism controls their maintenance and cell fate. This review w...

JOURNAL OF CLINICAL ONCOLOGY : OFFICIAL JOURNAL OF THE AMERICAN SOCIETY OF CLINICAL ONCOLOGY - 26 Dec 2019
To determine whether recommended amounts of leisure-time physical activity (ie, 7.5-15 metabolic equivalent task [MET] hours/week) are associated with lower cancer risk, describe the shape of the dose-response relationship, and explore associations with moderate- and vigorous-intensity physical activity.Data from 9 prospective cohorts with self-reported leisure-time physical activity and follow...

CARDIOVASCULAR DRUGS AND THERAPY - 30 Dec 2019
Drug-eluting balloon catheters (DEBc) coated with paclitaxel (PTX) have been associated with potential safety concerns. An efficacious but less toxic balloon coating may reduce these outcomes. We evaluated a novel DEBc, Epi-Solve, coated with metacept-3 (MCT-3), a member of the histone deacetylase inhibitor (HDACi) class of epigenetic agents, in a large animal model of neointimal hyperplasia (N...

MEDICINE AND SCIENCE IN SPORTS AND EXERCISE - 31 Dec 2019
To identify predictors of favourable changes to postprandial insulin and glucose levels in response to interrupting prolonged sitting time with standing or light intensity physical activity.Data were combined from four similarly designed randomised acute cross-over trials (n=129; BMI range 19.6 to 44.6kg/m2; South Asian=31.0%; dysglycaemia=27.1%). Treatments included: prolonged sitting (6.5hour...

JOURNAL OF HYPERTENSION - 01 Jan 2020
: The Lancet Commission on Hypertension identified that a key action to address the worldwide burden of high blood pressure (BP) was to improve the quality of BP measurements by using BP devices that have been validated for accuracy. Currently, there are over 3000 commercially available BP devices, but many do not have published data on accuracy testing according to established scientific stand...
